' lle it known that l, Tuoi/ras M. WORRELL,

"a citizen of the United States, residingat i. '.iliis invention relates to rcllenboarings, and has for an object `to provide a bearing embodying new and iniproved features of du# rability, utility, andnefliciency.

lt is .well lniown that in ball-bearings it is `considered necessary to torno the ball-race in the forni of a cup and cone or its equivalent to compensate for the Wear of the parts.

it is an objeetof this invention to provide a hearing adapted for any size shafting and machinery, but Vespintially adapted for use 'upon liieavy machinery where ball-bearings are found to be undesirable and embodying rollers and means for compensatingfor wear of the parte,

' i .si further object ofthe invention is to pro vide a bearing embodying split wear-iings against which the rollers contact and improved means for eontractingthe rings circuniferentiallyV to com ensate for weer by forming the exterior o the rings on a taper and te bearagainst the tapered bore ofthe boit'so that when the rings are forced into the {bon longitudinally of the shaft their circrniu ference is reduced. y

f With these and other objects in view the present invention consists inthe coinbination and arrangement of parts, as will be hereinafter fully described, shown inthe aeconipanying drawings, and particularly pointed out in the appended claims.

.ln the drawings, Figure 1 is a longitudinal see tional view of the improved roller-bearing. Fig. 2 a perspective view of one of the split wear-rings. Fig. 3 is a perspective view o'll one of the rollers and attached heads. Fig. 4 is a perspective View of one oi the pocketed collars by the use of which the rollers are properly spaced about the shaft.

- liilre characters of reference indicate corre- 'alponding parts in all of the figures of the raw'ings..

ln its preferred embodiment the improved Vrollcir-bcaring forming the suhject-niatteij of this application comprises a shaft 10 of any size and length and for any purpose and in which is formed a peripheral channel .11, having its sides 12 and 13 sulxstantiallv perpen dicular to the axis of the shaft. bout the pecicaton of' Lettere Patent.. rpplaieon leed Angie 30,1905. seien. 27a/toa ina-rented Magee, ieee.

shaft 10 are arranged the rollers la, ro ortioned for disposition. withinand wit t cir,V ends abutting the sides of the channel. .The rollers 14 are provided with axial s indles 15, 6o having at their ends disk-like hea s 16, concentric with but smaller than the rollers.` About the shaft are disposed the collars 17, having the pockets 18, in which the heads 16 are mounted, and slots 1,9, through which the 6 5 L spindles 15 pass properly spacing the rollers. cirouinferentia'llT about the shaft.y About .the rollers is disposed. a box 20, havin an 'openine 2l, through which extends the s aft 10, and provided internally with a ta ered 7o bore, as at 22, diametrically somewhat arger than necessary to accominodatethe rollers, and having a scievv-tln'ead 23'forrned inter- 1 nally in its larger and 'outer end. Within the 'box and between the walls of the bore and 75 the rollers are the wear-rings 21,1, split, as' at 25, on a line oblique to the edge and to ermit their contraction circumferentally. lhe rings 24 are continuously tapered on an an le` similar to the bore` taper of the box, andt ie 8o thinner edge of each `ring equals in thickness the thickeredge of the ring contacting, and the rings are provided. with tongueand-` groove connection, as at 26, with the tongues and grooves of all the rings equally distant 8 5` from the external surface, whereby as the inner surface wears new rings may be added and forced into the tapered bore.

'lo force the rings 24 within the box, a follower 27 is provided having screw-threads 28 9o proportioned to engage the threads 23 and a i trued edge 29, contacting with the external surface of the external ring. v'The follower will be provided with shoulders, angles,

notches, or teeth., as at` 30, for engagement by 9 5 l box the follower is provided with an opening 3l for that purpose and in alinement with the opening 21, otherwise the openinOP is omitted. roo To maintain the follower inthe desired position, a jam-nut 32 will be Vplaced upon the threads 28 and bind against the outer edge of the box and means, as at 33 and similar to the means designated at 30, will be provided for [o5 rotating the nut. l

From the foregoing description it will be readily understood that as the rollers and the internal surfaces of the rings 24 wear away the oilower 27 will be screwed into the box, I it forcing the rin s againstthe taperedsurface of the bore an contracting therein circum i, ferentially, andthe rings as they are worn out may be removed andreplaced by new ones, thus making it for all practical purposes im-l possible to Wear ythe bearing beyond the useful point.

-Having thus described the invention, what is claimed isl. In a bearing, a shaft, a pluralityv of split lrings encircling the shaft and tapered external y'on a continuous taper,I a tapered box about the rings and means for moving the tarollers and tapered lateral pered rings in contact withthe tapered box. 2. In a bearing, a shaft, a plurality. of rings having a continuous cylindrical bore.encir cling the shaft and each s lit obliquely to its edge and tapered externally on a continuous taper, a boxabout the rings and having a tapered bore within which the rings' are disposed and means for forcing the rings within .the box longitudinally of the shaft and to contract the rings circumferentially about the shaft.

3. In a roller-bearing, a shaft, rollers aroundthe shaft, split rlngs encircling the rollers and tapered laterally on a continuous taper and means to contract the rings. 4. In a roller-bearing, a shaft, rollers split rings' encircling the taper and means for moving the rings in v contact with a continuously-tapered surface tocontract them circumferentially.

y 5. In a roller-bearing, a shaft, rollers around the shaft, split rinfgs encircling the rollers and provided with tongue-and-groove connection and means to contract the rings circumferentially and simultaneously.

' 6; In a roller-bearing, a shaft, rollers around the shaft, split rings encirclincr the rollers and tapered laterally and providecIwith tongue-andgroove connection and means to contractthe rings circumferentially and si-` multaneously.

' 7. In a roller-bearing, a shaft, vrollers around the shaft, split rin s encircling the y and provided With tongue-andgroove connection and means for' moving the rings in contact with a tapered surface to contract them Acircumferentialhly.

8. In a roller-bearing, a shaft, rollersl vabutting tially.

9. In a roller-bearing, a shaft, rollers around the shaft, split rings encircling the rollers and tapered laterally with the thin edge of one ring equal in 'thickness Yto the thick edge of the next, a box surroundin the rings and having a tapered bore within tglich the rings are disposed and means for moving the rings in contact with the tapered bore of theu box to contract the rings circumferentia y.Y A

10. Ina roller-bearing, a shaft havin a peripheral channel, rollers about the shart and disposed in the channel and with their ends the sides of the channel, split rings encircling the rollers and tapered externally, a box surrounding the rollers and havin a tap red bore within which the rollers are isosed, means for moving the rings within the Eox lon itudinally of the shaft and toward the smalIer end of the box-bore. A

1 1. In a roller-bearing, a shaft having a peripheral channel, rollers about the shaft and disposed in the channel and with their ends abutting the. sides of the channel and having axial spindlesl and heads on the spindles, pocketed collars surrounding theshaft and with the heads of the rollers disposed within the pockets, split rings encirclin and tapered laterally and extern-a ly and having tongue-andgroove connections, a box surrounding the rollers and having a tapered bore Within which the rings are dis Josed, a4 follower bearing againstand arranged` to force the rings Within the tapered tract them ciroumferentially about the rollers and means for securing the follower at the desired adjustment.
